Sapphire knife has no metal

If you ever find yourself needing to sneak a knife pass a metal detector, this is a knife that has no metal parts. The handle is made from bone and the blade is made from an artificial sapphire that can only be sharpened with special diamond whetstone. I don't understand why anybody would need this, but hey, the more ways to stab people the better. That's what I always says.
